Charles Darwin published On the Origin of Species in 1859, [1] arguing that evolution in nature must be driven by natural selection, just as breeds of domestic animals and cultivars of crop plants were driven by artificial selection. [2] [3] Darwin's theory radically altered popular and scientific opinion about the development of life. [4]
Leaf variegation with white spots may serve as camouflage in forest understory plants, where there is a dappled background; leaf mottling is correlated with closed habitats. Disruptive camouflage would have a clear evolutionary advantage in plants: they would tend to escape from being eaten by herbivores. Another possibility is that some plants ...
[5] [6] These plants probably resembled liverworts, [4] and did not have any conducting tissues. [7] They were able to reproduce with spores , important dispersal units that have hard protective outer coatings which not only allowed their preservation in the fossil record, but also protected them from the UV light, desiccating environment and ...
Here are some of the most common plants that are toxic to dogs, according to Dr Wismer: Sago Palm This handsome prehistoric-looking palm is the most dangerous houseplant on the list for dogs ...
The possibility of protective coloration in plants has been little studied. T. J. Givnish and Simcha Lev-Yadun have proposed that leaf variegation with white spots may serve as camouflage in forest understory plants, where there is a dappled background. Lev-Yadun has also suggested, however, that similar markings serve as conspicuous warning ...

Camouflage enables an animal to remain hidden from view. Animals use colour to advertise services such as cleaning to animals of other species; to signal their sexual status to other members of the same species; and in mimicry , taking advantage of the warning coloration of another species.
Cryptic mimicry is observed in animals as well as plants. In animals, this may involve nocturnality, camouflage, subterranean lifestyle, and mimicry. Generally, plant herbivores are visually oriented. [1] [2] So a mimicking plant should strongly resemble its host; this can be done through visual and/or textural change. Previous criteria for ...
